Over the long weekend I had the chance to try other programs including Windows Media Player. NONE of them stayed connected to RR.
I also ran into situations this w/e where I was unable to reconnect. I would get messages the server was busy or unavailable; all while my two streams to RR were going out just fine. VERY FRUSTRATING.
I have no problems connecting to & staying connected to your feeds for several hours via WinAmp, iTunes, WMP, & the Web Player.
My guess is there is an issue on your end.
I see both your Sac feeds with good up time.
